実験手順

A mixed solution of a 6 N sodium hydroxide aqueous solution (0.02 mL) with water (0.06 mL) was added to a solution of [2-(4-{1-ethyl-1-[4-(3-hydroxy-4,4-dimethyl-pentyl)-3-methyl-phenyl]-propyl}-2-methyl-phenyl)-thiazol-4-yl]-acetic acid methyl ester (Example 63-(2); 15.9 mg, 0.0297 mmol) in methanol (0.4 mL) at room temperature, and the mixture was stirred at room temperature for 5.5 hours. The mixture was acidified with dilute hydrochloric acid aqueous solution, followed by extraction with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to give the title compound (15 mg, 100%).
